Stonehenge is a Neolithic and grounded until at least the Bronze Age-used building located near Amesbury in Wiltshire, England, about 13 kilometers north of Salisbury. It consists of a grave complex, which surrounds a Megalith structure, which in turn is composed of several concentric stone circles. The two most striking stone circles are an outer circle of stone pillars, which are bridged by cap jewels, and an inner horseshoe Trilithons structure of the original five (two keystones that) are bridged by a capstone. In between are other structures of smaller stones and holes in the ground. Other megaliths and two burial mounds are found in close proximity.
The emergence of the system can be roughly divided into three phases. The early phase of the plant, with a circular earthen wall and a moat, is dated to around 3100 BC. The striking Megalith structure was roughly between 2500 BC and 2000 BC built. The entire system is probably much older than previously thought. Accordingly, the Megalith structure was already around 3000 BC.
The UNESCO declared the Stonehenge, Avebury and Associated Sites, which include Stonehenge, a World Heritage Site in 1986.
